Given:
Base(b)= 3 inches ; height (h) =5 inches ; height of the prism is(H)=12 inches
Volume of the prism = Base area X height of the prism
[tex]\text{Volume of the prism=}\frac{1}{2}\times b\times h\times H[/tex][tex]\text{Volume of the prism=}\frac{\text{1}}{2}\times3\times5\times12[/tex][tex]\text{Volume of the prism}=3\times5\times6[/tex][tex]\text{Volume of the prism}=90\text{ Cubic inches}[/tex]
Therefore, Option C is correct answer.
